Game Freeze

While you wait in the Casual Matchmaking queue, the game just freezes. This has been happening frequently. You can't click anything. The timer and everything just freezes.
You get into a game and play it and go for another but everything just freezes. You have to restart to make it work again.
Fix, please?

This happens to me too. It freezes every time I Shift+Tab to bring up the Steam Overlay.

Hey! I sent a support ticket about this. I sent them logs and I ran Steam as admin and everything to try to work it out. I told them that the game freezes with Alt-Tab. Well, as a last resort, they told me to verify the game files in Steam. That seemed to do the trick! Hope that helps you too!
